Same issue here, just made a clean install not sure what it could be but seems to me that every time it happens time machine is running.
I just did a fresh install iMac 27 2020 what I suspect could be: 2 extra Crucial RAM 16Gb each or some App: Little Snitch, Paste, Tyme 2 or 2 external SSD case
panic(cpu 4 caller 0xffffff800d1f9a25): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 120 seconds
service: com.apple.logd, total successful checkins since load (2750 seconds ago): 276, last successful checkin: 0 seconds ago
service: com.apple.WindowServer, total successful checkins since load (2720 seconds ago): 260, last successful checkin: 120 seconds ago
service: com.apple.remoted, total successful checkins since load (2750 seconds ago): 274, last successful checkin: 0 seconds ago
